The AF-S Nikkor 24mm F1.4G ED is a wide aperture prime lens which is compatible with Nikon's FX (full frame) and DX (APS-C) DSLRs. It features an anti-reflective Nano Crystal coating and both ED (extra low-dispersion) and aspherical lens elements to help minimize distortion and chromatic aberration. Ideal for available-light and street photography, the 24mm F1.4 features a Silent Wave Motor for quiet autofocus operation with full-time manual focusing.
